You can find people in your device address book and add them as a Chalk contact. You can also add someone to your Chalk contacts by mobile phone number or email address. If they are Chalk users, you can call them after you add them to Chalk Contacts. If not, you can send them an invitation via Chalk, and when they sign up, you’ll see a badge appear next to their name in Chalk Contacts.
